摘要
介绍一种基于FPGA的双通道PXI数据采集系统,系统选用了PXI总线接口芯片PCI9030来实现功能电路与PXI总线间的通讯;采用FPGA芯片对整个硬件系统的工作逻辑时序的控制;同时介绍了数据采集系统的信号调理、AD转换、FIFO等电路;最后介绍了硬件驱动程序设计。仿真及调试结果表明,信号采样实时性和高速数据传输性能均满足要求。
A PXI two-channel data acquisition system based on FPGA was introduced.General PXI bus interface chip PCI9030 was selected to carry out the communication between the function circuit and the PXI bus.In the control circuit section,FPGA chip was used to carry out the logical timing control to the whole hardware system.The signal processing,AD conversion,FIFO circuit were introduced and the design of hardware driver was discussed.Both the simulation and experimental results show that the real-time sample and high-speed transfer of the system can meet the requests.
